Introduce common_val_print_checked
A (much) later patch will remove the call to value_check_printable
from common_val_print. This will needed to preserve some details of
how optimized-out structures are printed.
However, doing this will also break dw2-op-out-param.exp. Making the
change causes "bt" to print:
However, the test wants to see:
... operand2=<optimized out>
That is, a wholly-optimized out structure should not print its fields.
So, this patch introduces a new common_val_print_checked, which calls
value_check_printable first, and then arranges to use it in the one
spot that affects the test suite.
I was not completely sure if it would be preferable to change the
test. However, I reasoned that, assuming this output was intentional
in the first place, in a backtrace space is at a premium and so this
is a reasonable approach. In other spots calling common_val_print,
this behavior is probably unintended, or at least a "don't care".
